Application filed May 22, 1912. Serial No. 699,088.

To all LU/0772, it may concern:

Be it known that we, JOHN L. Focus and VnaGIL L. Foenn, citizens of the United States, residing at Fairbury, in the county of Jefierson, State of Nebraska, have 1nvented a new and useful Pump, of which the following is a specification.

This invention relates to pumps particularly designed for use for irrigation purposes, its object being to provide a device of this character adapted to be anchored in a current of water whereby said current may be utilized for the purpose of driving a water hoisting mechanism.

A further object is to provide means whereby the action of the current upon the apparatus can be controlled at the W111 of the attendant.

Another object is to provide a structure of this character which is cheap to manufacture, can be readily placed in operative position, and which will operate efficiently for the purpose intended.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings :Figure 1 is a plan view of the apparatus, a portion of the shield being broken away. Fig. 2 is a view partly in side elevation and partly in section. Fig. 3 is a side elevation of a portion of the apparatus and showing the shield in position for cutting ofi the water wheel from the action of the water current. Fig. l is an enlarged section through a portion of the water wheel. Fig. 5 is a transverse section through a portion of the shield. Fig. 6 is a longitudinal section through a portion of the pump. Fig. 7 is a side elevation of a portion of a modified form of wheel. Fig. 8 is a plan view of the mechanism combined with said modified form. Fig. 9 is a side elevation of a portion of a modified structure. Fig. 10 is a view showing in diagram another modified form of mechanism.

Referring to the figures by characters of reference 1 designates separate pontoons connected, at their ends, by cross beams 2 whereby the said pontoons are held fixed with relation to each other. A shaft 3 extends across the centers of the two pontoons and is journaled thereon, this shaft being provided, between the pontoons, with a water wheel made up of hubs 4L, outer rims 5 concentric therewith, rings within and concentric with the rims, as shown at 6, and radial spokes 7 connecting the hubs with the rings and rims. Transversely extending rods 8 connect the respective rims and pivotally mounted on these rods are blades 9 extending close to the rims and adapted to swing between the spokes. These blades are hung off center and, while passing under the shaft 3 are adapted to contact, at their inner ends, with stop rods 10 connecting the spokes 7 at points inside of the rings 6. During the rotation of the wheel the blades 10 swing successively downwardly so that their upper or inner ends contact with the stop rods 10. lVhile in these positions the blades pass between the pontoons and, as they rise from the water, they maintain vertical positions until they pass the horizontal plane passing through the shaft 3 whereupon the said blades assume lapped relations, as indicated in Fig. 1, maintaining these positions until they again reach the horizontal plane passing through the shaft 3 whereupon the blades swing downwardly to the active positions hereinbefore described and with their inner ends engaging the rods 10. Thus it will be seen that when the wheel is supported so that its lower portion will project into a current of water, the blades of the wheel will be successively contacted by the current and the wheel thus caused to rotate continuously.

A frame 11 is supported above the pontoons 1 and journaled upon one end portion of this frame is a shaft 12 having gears 13 secured thereto, any suitable means, such as a crank 1 f, being provided whereby the shaft can be rotated. The two gears 13 mesh with segmental gears 15 formed at the sides of a semi-cylindrical hood 16, this hood being pivotally mounted at points equidistant from the arcuate face of the hood, upon the shaft 3. Stop teeth or projections 17 are extended outwardly from the ends of the gears 15 and are designed to move against gears 13 so as to limit the rotation of the hood 16 about the shaft 3.

It will be understood that under normal 1 conditions all portions of the hood 16 are located above the pontoons 1, the hood thus serving to shield the upper portion of the wheel from air currents. By rotating shaft 12, gears 13 will be caused to rotate the segmental gears 15, thus turning hood 16 about its pivot shaft 3 and bringing one end of the hood into the water so as to shield the wheel from the action of the water current to any desired extent. By shifting the hood 90 degrees it will be caused to assume the position indicated in Fig. 3 and it will be appan ent that when thus located, the water current will be prevented from actuating the wheel.

As shown in Figs. 1 and 2, a sprocket 17 may be secured to the shaft 3 sons to transmit motion, through a chain 18, to another sprocket 19 secured to a shaft 20 journaled within one of the pontoons 1 and extending transversely thereof. A disk 21 is secured to this shaft 20 and has a wrist pin 22 8X tending therefrom and into a slot 23 formed within a head 21 from which piston rods 25 extend in opposite directions. Each of these piston rods is provided with a piston 26 mounted to reciprocate within a cylinder 27, the two cylinders being oppositely disposed and closed at their outer ends. An intake pipe 28 opens into one end of each of the cylinders 97 and has a check valve 29 therein while an outflow pipe 30 extends from each of the cylinders and is also provided with a check valve 31. The intake pipe 28 opens through the bottom of the pontoons. Thus it will be seen that when the water wheel is rotated, the pistons 26 will be caused to reciprocate within their respective cylinders. thereby sucking water throughv the pipes 28 into the cylinders and then forcing it outwardly through the pipes 30. As shown in Fig. 1 the outflow pipes 30 can. be connected to a single service pipe lnstead of utilizing the power transmitting mechanism shown in Figs. 1 and 2, the water wheel can be provided with a gear ring 33 meshing with a gear 34: connected to one end portion of a crank shaft 35 journaled on one of the pontoons. The crank of,

this shaft is substituted for the wrist pin 22 and is adapted to work within the slotted head 21 so that, as the shaft 35 rotates, the pistons within the cylinders 36, which are similar to the cylinders 27, will be reciprocated and the water thus elevated.

It is to be understood thatin using the device the pontoons are to be anchored in a stream of water so that the current will flow in the direction of the length of the space between the pontoons. This current under normal conditions will engage the blades of the wheel as they project successively below the surface of the water and the Wheel will therefore be rotated and cause the operation of the pump pistons. Should it be desired to reduce the speed of rotation of the wheel or to entirely stop the wheel, the shaft 12 is rotated so as thus to bring the hood 16 into position. at the upstream side of the Wheel. By partly lowering the hood only a portion of each blade will be engaged by the water current and the power of the wheel is thus materially reduced. By entirely lowering the hood, the water is out olf completely from the blades and the wheel will come to a stop.

Instead of'providing an internal gear such as shown at 33 in Fig. 7, an ordinary cog wheel 37 may be secured to the shaft 3 and employed for driving a gear 38 secured to the shaft 35.

As shown in diagram in Fig. 10 the shaft 3 may be provided with a crank 39 for transmitting motion through a pitman 10 to a lever 41 fulcrumed adjacent its center and connected, by means of one or more rods 4:2, to a piston rod 43 having pistons 44 at the ends thereof and adapted to reciprocate within opposed cylinders 45. Thus it will be seen that when shaft '3 rotates, motion will be transmitted through lever 41 and its connections to the pistons.

lVhat is claimed is The combination with spaced floats fixedly connected, of a shaft journaled upon and extending transversely of the floats, a water wheel extending between the floats and mounted on the shaft, a substantially semicylindrical hood pivotally mounted on the shaft and constantly housing approximately one half of the wheel, and means for rotating the hood to position it entirely above the floats or partly or entirely under the wheel, said hood, when entirely under the wheel, constituting a combined float and guard to prevent actuation of the wheel during the propulsion of the floats.

In testimony that we claim the foregoing as our own, we have hereto aiiixed our signatures in the presence of two witnesses.
